PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst for synthesizing unsaturated carboxylic acid, which is excellent in selectivity and yield of the unsaturated carboxylic acid. SOLUTION: The catalyst which is used when unsaturated aldehyde is subjected to vapor phase catalytic oxidation by using molecular oxygen to synthesize unsaturated carboxylic acid, and is a molded catalyst containing at least molybdenum and vanadium, wherein glucan where maltotriose is bonded to itsα-1,6 positions, is added to a particle containing a catalyst component and molding is performed.
